ABSTRACT

Parreysia cylindrica is an edible bivalve belonging to phylum Mollusca, class Bivalve and family Unionidae. It is abundantly found in fresh water. The bivalve Meat is white and tasty. Whereas most food sources for the humans are provided from fresh water flora and fauna, now a day’s bivalves has been functionally used as another good source of food nutrients to man compared to fresh water animals. This bivalves meat known to be good sources for the provision of protein, carbohydrate, lipid, amino acids, fatty acids, vitamins and minerals. This study was conducted to assess the nutritional qualities of P.cylindrica of the Waddepally and Kaleshwaram in two different lakes. The total protein content was found to be varied between 55.67% and 40.21%. The carbohydrate concentrations were ranged from 5.21 to 16.67% and lipid were ranged from 6.63 to 2.11% respectively at the Station I and II. The total essential amino acids were ranged from 14.28% to 0.33% and non-essential amino acids were 7.35 to 1.15% at Station I and II. Total saturated fatty acid, monounsaturated fatty acid and polyunsaturated fatty acids were determined. The vitamin A, vitamin D, vitamin E, and K of vitamins were 15.40IU, 300IU, 2.18 mg/g and 0.72 mg/g from the Station I and 9.200IU, 200IU, 2.08 mg/g and 0.19 mg/g found from Station II. Totally, 4 macro minerals and 2 trace minerals were detected from both the stations.
